SPECIFICATION forming part of Letters Patent No. 395,270, dated December 25, 1888.

Application filed November 12, 1886. Serial No. 218,685- (No model.) Patented in France August 11,1883, No, 166,996,- in England May 19, 1884,1l0. 7,988, and in Germany May 28,1884,1 T0. 31,006.

To (all whom it may concern.-

Be it known that I, MARIE IIYACINTHE FOUILLET-OHEVANCE, a citizen of the French Republic, and a resident of Neauphle 1e lhateau, Seine and Oise, France, have i11- veuted certain Improvements in Braiding-Hachines, (for which invention Letters Patent have been granted in France August 11., 1883, No. 156,996 5 in England May 19,1884, No. 7,938, and in Germany May 28, 1884, No. 31,006,) of which the following is a specification.

In my Letters Patent No. 363,627, dated May 24, 1887, I show and describe a binding-braid made primarily with a longitudinal fold, which is effected by forming a selvage along the line of fold on one side of the braid. \Vhen the braid issues from the machine, it presents the appearance of a strip of braid folded longitudinally, pressed flat, and provided with a selvage along the folded edge, formed by a peculiar interlacing of the threads.

My present application relates to a machine for making this kind of braid; and the novel features of the machine consist partly in the mechanism whereby the threads are so interlaced along a predetermined line in the braid as to produce a longitudinal fold and selvage, and partly in means employed in connection with that above referred to for delivering the braid in a folded condition, all as will be hereinafter set forth.

In the drawings which serve to illustrate my invention, Figure 1 is a plan of a braiding-machine embodying my invention. The reel and other mechanism for taking up the braid are not shown in this View. Fig. 2 is a sectional elevation of same, designed to illustrate the mounting of the spindle-carrying disks. Fig. 3 is a sectional elevation of same seen at right angles to Fig. 2. Fig. 3 is an enlarged sectional detail view, which will be referred to hereinafter. Figs. 4:, 5, and U are diagrammatic views illustrating modifications in the arrangement of the supplementary spindle-carrying disks, and Fig. 7 is a diagram illustrating the interlacing of the threads which form the median selvage. Figs. 8 and 9 are cross-sections of the braid made on machines embodying my invention.

I will only briefly describe that portion of he machine which possesses no novelty, and which may be found in the ordinary machines for making fiat braid.

A is a suitable frame in which are rotatively mounted in a circle vertical shafts a bearing the spindle-carriers A A, and D is the driving-shaft, on which are mounted tight and loose pulleys E E. On shaft D is a bevelwheel, F, which meshes wit-h a similar wheel, G, on the shaft ta of one of the carriers A. On the same shaft, a is a pinion, I, which meshes with and drives an intermediate spur-wheel, H, and this spur-wheel meshes with three other pinions, I, on the shafts a of spindlecarriers A, arranged at equal distances around the circle. Thus movement is transmit-ted to four of the shafts ta and these four transmit it to all the others through the medium. of toothed wheels J on the several shafts a Each spindle-carrierAhas four notches or recesses, Z), in its periphery to receive and transmit the spindles, and the two terminal spindlecarriers A A which turn the spindles and send them back, thus forming the ordinary selvages of the braid, have each five notches b.

O O O up to O represent the spindles which carry the thread spools or bobbins O (Seen in Fig. 2.) The carriers cause these spindles (all following the same path) to move in a serpentine manner back and forth from one end of the series of carriers to the other, moving in returning in a path oppositely flexed to that in going, and thus interweaving or interlacing the threads.

L L are needles extending from the axis of carriers A to the funnel N at the center of the machine. These are designed to prevent the entanglement of the threads at this point.

M M are the heaters, which are actuated by a crank, 19, through the medium of bell-crank levers Q. beaters will be more minutely described hereinafter.

c 0 represent the various threads which extend from the various spools O to the funnel N.

The above-described mechanism is the same substantially as that employed in the ordinary braid-making machines.

I add to the machine a supplementary The mechanism for actuating these 1o ing the piece R adjustably 011 the bar S.

beater, M, (seen in dotted lines in Fig. 1,) the free end of which stands close to the funnel N. This beater is connected by a rod, 0, to one of the bell-cranks Q, and is actuated thereby.

S is a bar projecting out over the machine, which bar has an adjustable extensionpiece, R, in which is mounted the funnel N. In Fi g. 3 I have shown the manner of mount- Said piece R has a longitudinal slot, formed in it, and a clamping-screw, 1', passes through this slot and screws into the bar S. There may be two or more of these slots and screws. Any means of securing the extension-piece adjustably to the bar may, however, be employed. The adjustment of .piece R enables the funnel to be brought exactly into the axis or center of the machine. The piece R also carries two vertically-arranged pins, 0' a", between which the folded braid passes, and from these the braid passes over a roller, 8, also mounted on piece B. These pins forma narrow passage for the braid to pass through, and serve to bring the two plies of the braid together and to flatten it, so that it may be eventually rolled up in this condition.

Over the machine is mounted a reel, U, to receive the finished braid. This reel is driven from a shaft, T, through the medium of a belt and pulleys, T which shaft is driven. through the medium of a 'wornrwheel, Z, thereon and a screw or worm, X, on a vertical shaft, V. ShaftVis driven from the gearing of'the machine below in any convenient manner-as, for example, from one of the toothed wheels J-through the medium of an intermediate spur-wheel, the latter meshing with a toothed wheel on shaft V. 011 shaft T is a cone-pulley, T, over which the braid passes from the machine to reel U. The braid (indicated in Fig. 2 by dotted lines Y) may pass over either of the sections of the cone-pulley T, and this enables the operator to make the braid loose or close in texture at will, because the speed at which the braid is drawn from the machine will depend upon which section of the pulley T it passes over.

I will now more minutely describe the mechanism employed for actuating the beaters M M and the auxiliary beater M, with special reference to Figs. 1 and 3. On shaft V is a sheave,. and on a shaft, P, arranged parallel with shaft V, is a sheave, J. A driving-belt, J connects sheaves J and J, and through the medium of belt J 5 shaft V drives shaft P. On the upper end of shaft P is fixed a crank, 19, and to the wrist-pin or crank-pin of said crank 19 are coupled the one ends of two connecting-rods, p p, the other ends of which are coupled, respectively, each to one arm of one of the vibratory bell-cranks or bell-crank levers Q Q. These bell-crank levers are mounted, respectively, on shafts or pivots Q Q. Two vibratory levers, Q 43 are mounted on shafts or pivots Q Q respectively, and to the one arm of each of these levers Q is attached one of the beaters M. The other arms of saidlevers Q are coupled each to one of the arms of the respective bellcrank levers Q by means of a connecting-rod, p that is to say, one beater, M, with its vibratory lever Q and bell-crank lever Q, is ar ranged at each side of the bar S. The crank 19 actuates both beaters through the intermediate mechanism described.

In order to determine a longitudinal fold in the braid, and to form a selvage on one face of the braid along said fold, I interpose near the middle of the series of ordinary carrierdisks, A A or at any point therein, an intermediate disk, A, having but three notches b, and outside of the series of disks and adjacent to the'disk A a supplementary carrierdisk, I3, having seven notches Z).

In tracing the movements of the spindles we may begin with spindle O and suppose that it starts from its position indicated in Fig. 1, in which case it will occupy, successively, the positions 0 C C O C O C C C C C C C C C C C on the carrierdisks at the left in Fig. 1. ferred by the intermediate carrier-disks, A, to the supplementary disk B, and occupies in this disk, successively, the positions C C 041 038. A, occupying, successively, the positions 0 C45, (1 17, 049, 0517 C C57, C09, 061, O63, O C, C, C C C and C on the carrierdisks A and terminal carrier-disks A at the right in Fig. 1. In returning, afterbeing carried around disk A the spindle occupies, successively, the positions 0 U C C C C C62 C60 C58 C56 C54 C50 C48 046 th without passing around the supplementary di k 1) 7 t C36 C34 C30 C28 C26 C24 C22 020 C18 C C C C C C C C (on terminal disk A at the left) C and again to C. Thus it will be seen that while the disks A bear the spindles along in a sinuous path the terminal disks A give this path a loop-like shape, thus forming the edge selvages of the braid, while the supplementary disk B, in conjunction with the intermediate disk, A, gives to the spindles path a loop-like form when they are traveling in one direction, therebyforming or throwing up a selvage along the median line of the braid and on one face of same. The formation of this median selvage causes a contraction on the opposite face of the braid, which, in conjunction with the fullness imparted in forming the selvage, determines a fold along thisline, and thus produces a primarily-folded braid.

The diagram Fig. 7 sufficiently illustrates the sinuous path of the spindle and the loops in same formed at the selvage-points.

WVhen the supplementary carrier-disk B is arranged exterior to the circle, as in Fig. 1, there is a slight inconvenience arising from the fact that the strain is greater on the thread when the spindles are passing around said disk 13, and the median selvage will not be exactly in the middle of the braid. In Fig.

Then it again passes to carrier-disks Then it is trans- IIO 1, for example, there are eighteen carrierdisks at the left of disk A and but seventeen at the right. I may, however, arrange the supplementary disk B interiorly, as in Fig. 4, and thus relieve the thread from undue strain, and at the same time place the median selvage exactly in the center of the braid. In this view the intermediate disk, A, and the supplementary disk B both have three notches for the spindles, and an equal number of four-notched disks A will be arranged on either side of the disk A. The disk B being smaller in this case than that seen in Fig. 1, the selvage formed thereby will naturally be less prominent. By arranging disks A and B more or less to the right or left, the median selvage may be placed nearer to one edge than the other.

A braid for binding very thick materials may with advantage have two median sel vages arranged at the proper distance apart. Two such selvages may be formed and two folds be determined by employing two intermediate disks, A, and two corresponding supplementary disks B, as seen in Fig. 5. In this case both disks, as in Fig. i, have each three notches for the spindles O. The number of disks A between the disks A must in this case always be uneven, as 3 5 '7, &c. In Fig. 5 three are shown.

In Figs. 4: and 5 the spindles indicated in full black tint move in the path indicated by dots and move in the direction indicated by arrow 00, and the spindles indicated only by circles move in the path indicated by broken lines and in the direction indicated by arrow y In these modified forms of the machine the intermediate and supplementary disks, having but three spindle-notches, each must revolve with a velocity one-fourth greater than the disks with four notches. This excess of velocity of the two disks with but three notches is necessary to permit them to pass the spindles properly but it may produce undue strains or shocks on the thread and consequent frequent breakage thereof. This produces faults in the braid. To avoid this it is necessary to run the machine with less speed than the ordinary machines are run, and therefore the yield therefrom is less. In Fig. (3 I show an arrangement that does not present these inconveniences. In this construction the intermediate disk, A, has five spindlenotches l), and the supplementary disk B has but three notches and is arranged interiorly. This arrangement permits the machine to be run at a speed equal to that of the ordinary machines. In this figure the course and direetion of the spindles are indicated in the same way as in Figs. 4 and 5.

It will be obvious to those skilled in this class of machines that either of the arrangements of the intermediate and supplementary carrier-disks A and B shown in Figs. 4, 5, and 6 may be substituted for that shown in Fig. 1.

Fig. 8 illustrates in cross-section the braid with a single fold and median selvage as produced by either of the arrangements shown "in Figs. 1, 4, and (3. e 6 represent the two plies of the braid, and the median selvage along the fold.

Fig. 9 represents in cross-section the species of braid produced by the arrangement seen in Fig. 5, which produces two median selvages. e 6 represent the two plies of the braid, e e the two median selvages, and c the web of bra-id between theseselvages.

It will be observed that one of the characteristic features of my machine is the introduction into the series of ordinary spindlecarrying disks A of an intermediate disk, A, having an odd number of spindle-notches b, and a supplementary selvage-forming disk, B, operating in conjunction with disk. A. The function of disk A is to carry the spindle out to disk B when said spindle is traveling in one direction and to pass it on from one disk A to the next when it is traveling in the other direction. The function of disk B is the same in substance as that of a terminal disk, A that is, to form a loop in the undulatory path of the spindle when it is traveling in one direction. The disk B is always outside of the series of disks; but it may be, asI have shown it, arranged either eXteriorly or interiorly to the circle of disks.

I have not considered it necessary to show in Figs. 1, 2, and 3 all the various parts of a braid-making machine, as these machines are well. known. Enough is shown to enable any one skilled in the art to apply my improve 'ments thereto without difficulty.

I am aware that it is not new to employ in a machine for making tubular braided fabrics with two oppositeselvages extra spindle carrying disks to form the selvage, said extra disks each having an odd number of notches; but in this machine the main series of disks have all a like number of notches, while the spindles travel around continuously in one direction, producing a tubular fabric and not a binding-braid. In my machine the spindles travel back and forth from end to end of the series of disks, the terminal disks for forming the edge selvages having an odd number of notches. I am also aware that in machines for making longitudinally-divided fancy braids exterior or side carriers or disks have been employed in connection with directors to turn the spindles and send them back, thus performin g,when brought into play, the functions of my terminal disks A This I do vnot claim. The peculiarity of the operation of my supplementary disk lies in this, that the spindles pass around said disk when moving in one direction, but avoid it on the return. Thus the braid is not divided longitudinally, but folded.

Having thus described my invention, I claim- 1. In a machine for making a folded braid, the combination, with the main spindle-carrying disks A, arranged in series and all having the same and an even number of notches, and the terminal edge-selvage-forming disks A for returning the spindles, each of which has an odd number of notches, of an intermediate spindle-carrying disk, A ,in said series having an odd number of notches, and a supplementary spindle-carryin g disk, B, having an odd number of notches arranged out of the series and adjacent to disk A, whereby said spindles, when passing in one direction, are caused to pass around the disk B, and when moving in the other direction to avoid said diskB, as set forth.

2. In a machine for making a flat bindingbraid with three selvages, the combination, with the disks A, arranged in series and havin g each four notches Z), and the terminal disks A for forming the edge selvages, each having five notches, of the intermediate disk, A, arranged in said series and having :[ive notches b, and the supplementary disk B, arranged outside of said series and adjacent to disk A, said disk B having three notches Z9, whereby, when moving in one direction, the spindles are caused to pass around said disk B, and when moving in the other direction to avoid said disk, substantially as set forth.

A machine for making a longitudinallyfolded braid, provided with two pins, r- 0", which form a narrow passage for the braid on its way from the machine and whereby the two plies of the braid are properly brought together.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
